Hi @steve1368
Sorry you are experiencing these problems, could we get some details?
1. Some of the screens are so different from training videos in terms of layout or formats;
*Cloud has been changing fast, would you mind to indicate what are you looking for that are not able to find?
2. Sometime the screen becomes so BIG that I could not read ALL in one screen;
*This is weird, would you mid to show a screenshot that shows the issue?
3. I am still unable to develop a simple Table chart as system hanged all the times;
*Does this happen if you use different browsers? If you open the browser developer tools, do you see any errors under "Console" or "Network" tabs?
4. Cannot find refresh option for data and report;
*Do you mean reload? In the hub where the apps can be found, the app have three dots, there is an option to Reload or Schedule a reload.
5. Not sure why old data files uploaded previously and stored in cloud cannot be deleted under Catalog;
*This was brought to our attention recently, can you attempt to do it through the Script Editor? There should be a Data Connection to files, then when you click on it as if you were adding a file, instead you can click the delete button.
6. May I know what is the function of Catalog and Collections?.

I would suggest to create a new thread for the Screen issue, as best practice we suggest to open a separate post for each question, that will prevent confusion when it comes to identify what questions were answered and which ones are still pending.
Hope it helps!
